Figure Irepresellls the plan of my invention. Figures 'II andthofadj'ustable connections of'the ploughs. Y The nature of my inventionconsists in theconstru'ction et' a plough orcultivator both'si'mplc andcheap, n'liichw'ili, with onel manv vand. one horse, cultivate the sameamount of corn that can be cultivated with n sully plough with twohorses,Vv or double the amount cultivated by any other plough orcultivatornwith the saine team. l

. To enable othersv skilled-in the art tomakc and use my invention, Iwillproceed vto describe its construcrepresented in Eig.' I. yI alsoconstrnct'athird plotfgh, with a beam, B', aboutI two-thirds the lenffthof the beams B B, to the end ofwhich Iattacll an upright, G', by a.mortise, to which is attached a shovel, C'g" Y' I construct two ploughs,with beains B B, handles vF F, uprights G G, lto which I attachshovelsC, as n 'T hethfree sections of the cultivator `jnst described areconnected at the front end by a` semieircuI arfshaped laten of ironloran other suitable nnaterial havinrf in it several holes to enable the oexc-,ttor to refrnlate s s a r P o thooutside shovels, so as to"throw'the dirt to oilfrom the corn at pleasuro. .Tothe centrehole'ofthisplate IV 'attach the end of the beam B', by meansof a mortiseand an iron bolt. The ends of beams BB are attached byclevise's in theout-er lholes of the plate. In the centre of this plate,vand in frontof' the end of bcarn'B, is a hole in which to 'put the clevis ofWhiBle-tree. i I

I attach theuprights G byan adjustable slide,'oi` iron, or any othersuitable material, asrepresented in Fig. II, having eye at eachend, inwhich is put a bolt, by meansofa' hook, forming a hook-and-eyejoint, bywhichthcyarebolted together# In the slide are several holes, to enablethe operator to adjust the ploughs to rows of diilerentwidths.` Theslides are secured by ineens of bolts represented by H, Fig. II.

.By Fig. 'III, I"rep rescnt across-piece of i1jon,or any other `suitablematerial, n-the centre lot'v which a bolt-hole, by means of which itisbolted to upright, G', in a. suitable place. These ends lare attachedVto beams B B inthe same manner `as represented in the slide referredtoin Fig. III, with exception of one additional tap onthe inside yof beamsB B, "byrneans ot' which the piece can be shortened or lengthcnedatlwill.

The use of the crosspiece D is to lift the centre shovel out @fthcground with either of the other two. lThe use of the hool-andyejointsin slides Dand'E is to enable the cultivator to adjust itself to theuneven` nessof surfaces, to aller each of the outer shovels, singly ortogether, to be moved up or down or laterally, or

in any direction, so that the loperator has coniplete control of thecultivator.Y
